VS 2008 - Microsoft.VisualStudio.DataDesign.SyncDesigner.SyncFacade.SyncManager Error

I experience the following error message when I wanted to get connected to a database on a SQL 2008 Express from a machine with a newly installed Visual Studio 2008.

When I tried "Add New Data Source" and after creating connection string at the time of proceeding to finalize the connection, the Error Message came up:

Could not load type 'Microsoft.VisualStudio.DataDesign.SyncDesigner.SyncFacade.SyncManager' from assembly 'Microsoft.VisualStudio.DataDesign.SyncDesigner.DslPackage.Version=9.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.

The simple solution which worked for me was installing VS 2008 SP1, at this moment it's available at:
